So i did everything i could to get rid of my death wobble. i replaced all four ball joints, all three TREs, new drag link, rebuilt track bar, pro comp steering stabilizer, energy suspension swaybar bushings, and WJ sway bar links. The steering is tight and she rolls great other than exatcly at 45mph to 50 mph she starts to wobble. I thought it was just because my tires need balancing so i dealt with it. It has started to get a little worse so i stuck my head out the window and you can see my tire wobbling. I'm also haveing a problem with serious tire wear on the driver side front. Its odd just because it really is strictly to the 45 - 50 mph range. I'm at my wits end with the freakin jeep right now, also have bad rod bearings, so any help is gonna be pulling this thing away from me driving it off a cliff and calling the insurance company.

 

Have you checked your wheel bearings?

 

yup, probably your wheel bearing/ hub assembly. Also, maybe a tire with a broken belt could cause a bubble, or maybe your axle shaft u joints are bad?
Good Luck!

 

i did notice a little bit of bubbling on the tire. Almost like its to tight between the rim and tread. Not sure on the wheel bearings but i do have spares so that is gonna be my next step.

 

my jeep does the same thing at 55 to 60 mph...all the steering components are tight....thinking that its my wheel bearings also? are wheel bearings hard to replace?

 

they are pretty easy. take off the hub nut, the caliper, the rotor, then remove the three torque bit bolts that hold the bearing to the steering knuckle. They have a tendency to rust up in the knuckle so have a big *** hammer ready. Use anti sieze when installing the new one.

 

Haven't seen alignment mentioned. Bad alignment will cause abnormal wear on one or more tire and have a huge affect on death wobble. When's the last time the alignment was checked?

 

A death wobble is usually cause by axle not being centered when you are driving straight.
It could be loose trackbar, worn out bushing or you might need longer trackbar if you have lifted your jeep.

A vibration could be a few things but i would check the pinion angle to start with if you have lifted your jeep.

GL.

 

Just rebuilt the track bar, my geometry looks good, i measured the front tire stick out from the fenders and there are within 1/4" of each other and i already added caster shims to tighten up the pinion angle. My control arms are stock with 211000 miles on them so those bushings are probably past thier prime

 

Sorry, i missed that rebuilt trackbar part .

In that case, why don't you jack up the Jeep and see if there is any movement on the arms and at the same time check for wheel bearings and ball joints play.



Hope i can be of more help.

 

brand new ball joints too. I'm gonna replace the wheel bearings this week and do the alignment because i know it's pulling to the left anyway.
